Photo caption: Sand Island Light has marked the entrance
to Mobile Bay and the Mobile Ship Channel since 1873. The oldest light
in Alabama, it is the third light to stand on this small island. Granite
molding defines the polygon-shaped base. On the interior, an iron circular
staircase leads to the watch room. Above the watch room, the glass lens
room is topped with a conical copper roof. (Photography courtesy of Lacey
